FRIC'IIONAL HINGE DEVICE.

Application 'led .Tune 21, 1926. Serial No. 117,320.

rllhis invention relates to friction hinges for holding hinged doors or windows in any position in which they may be set. If a door or Casement window provided with an ordinary hinge is allowed to stand open it is easily moved from this position and such doors or windows frequently blow shut, which not only prevents the door or window from being kept open when desired but causes objectionable noise due to the slamming shut of the door or window.

The main object of. the present invention is to provide a device or .attachment which may be readily appliedto an ordinary hinge of a door or Casement window or other hinged object, and by means of which sufficient friction may be exerted upon such hinge to cause the same to remain in any position in which it is set, against the action of the ordinary `forces tending to move such object from such position. A further object of the invention is to provide .a fric tion hinge which may be quickly and easily loosened or released to permit turning movement of the hinge when desired. A further object of the invention is to provide a hingev which may be held in any desired position by friction alone, so that in the case of the application of an unusual force such `as a sudden effort to move the door or window the hinge may be moved against this friction without breaking any of the parts of the device.

Our invention consists essentially in a friction attachment for hinges, comjirisingv a member embracing the ends of the hinge joint, and means for engaging said einbracing member and the parts of the hinge in such manner as to exert a frictional force on the parts of the hinge to hold the same in position. rlhe invention should also be understood, however, as including the entire assembly, including the hinge with a friction device of our invention applied thereto.

The accompanying drawings illustrate embodiments of our invention and referring thereto:

Fig. 1 is a plan view of a easement window hinge provided with a friction device according to oui1 invention, the adjacent portions of the window and the casing being shown in sect-ion.

' Fig. 2 is ahorizontal section of the same on line 2 2 in Fig. 3 with the window in open position. l

Fig. 3 is a side elevation of the hinge,

Fig. 4 is a vertical section through the joint of the hinge on line in Fig. 2.4

Fig. 5 is a side elevation of a modified form of friction device.

Fig. 6 is an end view of the same.

Fig. 7 is a view similar to Fig. ,4, showing the application of the invention in connection with an ordinary door hinge,

In Figs. l and 2 the easement window l is mounted on casing 2 by means of a hinge. of any ordinary type comprising two leaves, such as straps or butts 3 and l secured respectivcly to said window and said casing, said leaves being ordinarily pivoted by a hinge pin passing through the usual aligned openings in an intermediate knuckle or barrel portion 5 Yon the leaf 3 and end knuckles or barrels 6 on lea-f 4. The device of our invention for applying friction to such a hinge comprises means such as bracket 7 eX- tending alongside the joint of the hinge and embracing the ends of the hinge joint, and having at its ends sleeve or barrel port-ions 8 whose threaded openings 21 are adapted for alignmenty with the openings through the knuckles or barrel portions 5 and 6 of thc hinge. vThe ordinary hinge pin is removed and is replaced by a loose central pin 9 cX- tending within the knuckle 5 and part of the way through each of the knuckles 6, and two threaded end pins 10 screwing through the barrel portions 8 and into the respective knuckles 6 so as to hold the loose pin 9 in position. The threaded pins 10 may be provided with slots 1l to receive a screwdriver or other suitable rtool for screwing such pins into position and such pins may if desired be ball-shaped at their outer ends so as to resemble the ordinary hinge pins.

A wing bolt 12 is screwed into an inter nally threaded recessl in the bracket 7 and is pointed at its end as at '14 so as to press into the metal of the central knuckle or barrel portion 5 and set itself as indicated at 15, thus substantially clamping the bracket 7 to the -leaf 3 of the hinge.

By tightening up on'wing bolt 12a lateral thrust is exerted between the bracket 7 and knuckle 5 so that pins 1() are slightly displaced laterally with respect to the pin 9, and friction is thus exerted between such pins and the knuckles or barrel portions of the hinge at the points or surfaces indicated at Such friction effectively holds the hinge member in any position in which it may beY set, and prevents turning thereof by any force which will ordinarily be applied thereto for example by a wind blowing through the window. At the same time however if any one unaware of the fact that the hinge is secured in this position attempts to shut the window and exerts an unusual force thereon the hinge may be moved against this friction without damaging any parts of this device. 7 hen it is desired to close the window or door, or to move the same to a different position, wing bolt 12 may ordinarily be loosened sutiiciently to relieve thefriction and permit easy turning of the hinge.

Other means may be employed for causing the lateral displacement of the pins 9 and 10 required to produce the friction against the knuckles or barrels of the hinge. For example, as shown in Figs. 5 and 6, a cam member' 16 having a bevelledor sharpened edge 17 may be pivotally mounted at 18 on the bracket 'i' and may be provided with a projecting handle 19 for operation thereof. ViThen handle 19 is pressed down against the bracket so as to rotate cam member 16 in the direction indicated by the arrow, the bevelled edge thereof is pressed more firmly against knuckle or barrel portion 5 so as to exert the required lateral thrust against such portion. The provision of av bevelled or sharpened edge on the cam member is for the purpose of causing the same to cut into the barrel portion sui'iciently to setitself. therein in such manner that it will remain-in any position in which it is set, until relieved by means of handle 19.

In Fig. is shown the application of our invention to a door hinge in which one of the leaves or butts 3 of the hinge is provided with two knuckle portions 5 and the other leaf or butt l is provided with three knuckle portions 6. The bracket member 7 as before embraces the ends of the joint of the hinge and is pro fided with threaded pin 10 screwing into the barrel portions 8 of said bracket member and projecting somewhat for example approximately half way through itl to their knuckle portions 6. AQ loose pin 9 extends in this case through the central knuckle portion 6 and the two knuckles 5 and part way through the two end knuckles G as shown. The wing bolt 12, which is mounted as before, is placed in position toengage either of the intermediate knuckle portions 5 or if desired similar means may be provided for pressing aga-inst both of said knuckle portions. The other features of the construction and the operation of the device are substantially the same in this case in the form first described. The points at which friction is exerted upon tightening of the wing bolt 1&2 are again indicated at 7We claim:

1. A friction hinge device comprising, in combination with a hinge having. a pair of leaves provided with alternating knuckle within the openings of said knuckle portions` between said first-named pins and means mounted on said embracing member and adapted to engage an intermediate knuckle et Ithe hinge to exert a relative lateral thrust between said knuckle and said embracing member.

il. A construction as set forth in Vclaim 1 in which said thrust exerting means comprises a wing bolt screwing through said embracing member and bearing at its inner end against said intermediate knuckle of the hinge. 1

8. A friction hinge device comprising, in combination with a hinge having a pair of leaves one of which is provided with a knuckle portion at each end of the hinge joint and the other of which is provided with a knuckle portion intermediate said end knuckle portions, a member embracing the ends of said hinge joint, means on said emw bracing member and engaging said end knuckles in such manner as to exert lateral pressure against the same, .a pin extending through said intermediate knuckle and also engaging said knuckles in such manner as to exert a lateral pressure against the same, and means mounted on said embracing member and engaging said intermediate knuckle in such manner as to exert a relative lateral thrust between said embracing member and said intermediate knuckle.

e. A friction device, for attachment to a hinge having a pair of leaves one of which is provided with two end knuckle portions and the other of which is provided with an intern'iediate knuckle portion, comprising a member adapted to extend alongside the joint of such hinge and having end portions lUt:

embracing the said end knuckles, means on said end portions for engaging said end knuckles in such manner as to exert lateral pressure against the same, a pin adapted to extend through said intermediate knuckle and to also engage said ,end knuckles in such manner as to exert a lateral pressure against the same.l and means mounted on said embracing member and adapted to engage said intermediate knuckle in such manner as to exert a relative lateral thrust between said embracing member and said intermediate knuckle.

In testimony whereof we have hereunto subscribed our names this Qth'day of June,
